What kind of riding do you do/looking to get out of a resort? Park/Powder/Steeps/Chutes/Bowls/Trees/Cliffs?
There are a lot of choices in SLC/Utah. Each offering something different.
But be aware, that no matter where you go in the US/CA december 3rd is very early in the ski season, so a lot of places wont have speculator coverage. But UT/CO/PNW will have more than most.
